Linux TV support Elgato EyeTV hybrid

[Gilles Risch]

Hello,

I'm owning an Elgato EyeTV hybrid USB stick that I'm using daily on my
iMac, now I'd like to use it on my laptop too but I'm unable to get it
running. Is this device already supported? If not, is there any way I
can help? I've already opened my device and uploaded the photos to the
linux TV wiki page
(http://www.linuxtv.org/wiki/index.php/Elgato_EyeTV_hybrid).
I'm not sure which tuner is mounted on the PCB, therefor I've made two
USB traces, maybe someone could interpret them and conclude which one
is used:

Kind regards,
Gilles

Hi Gilles,

Not sure if the following information will help you, but here comes.
The USB bridge is EM2884, supported by em28xx driver. The Micronas
demodulator is probably supported by drxk driver. Tuner I did not
recognize after a quick glimpse. That sandwich construction look like
something PCTV has used with some of their designs (290e and 292e for
example).

In order to have a driver for your device you need to have each
individual component supported (USB bridge, demod and tuner). Then
these can be combined into a driver (typically by modifying the USB
bridge driver).

Cheers,

Hi,

most of the used components are identified:
- USB Controller: Empia EM2884
- Stereo A/V Decoder: Micronas AVF 49x0B
- Hybrid Channel Decoder: Micronas DRX-K DRX3926K:A3 0.9.0
The only ambiguity is the tuner, but I think it could be a Xceive XC5000 
because the windows driver comprises the xc5000 firmware and it is 100% 
identical:
     $ mkdir extract-xc5000-fw
     $ cd extract-xc5000-fw
     $ wget http://linuxtv.org/downloads/firmware/dvb-fe-xc5000-1.6.114.fw
     $ wget

     b1ac8f759020523ebaaeff3fdf4789ed  dvb-fe-xc5000-test.fw

The Elgato_EyeTV_Hybrid.inf file contains a comment with "TerraTec H5", 
which components are assembled on that USB stick?

This sounds like the Hauppauge WinTV HVR-930C:

The TerraTec H5 has a TDA18271 tuner.

So most likely the Elgato EyeTV hybrid is one of these combinations. And 
it should quite feasible to add support for someone who knows the Empia 
EM2884.

It is pretty similar than 930C but not same. Compare pictures from my 
blog and those on LinuxTV wiki. PCB is different.

That device could be supported just making proper board profile to 
em28xx driver. Rather trivial stuff to one who has any experience. Just 
one hour work or so.

I don't see the tuner chip, so it could be a tda chip.

Applying version 2 of that patch was successful. Creating a channels 
file with w_scan worked too and I'm able to watch TV. The remote control 
doesn't yet work. Next weekend I'll try to create a board file.

Thanks for the support.

Re: Linux TV support Elgato EyeTV hybrid

[Gilles Risch]

Hello,

watching TV now works fine, but I still have a strange behavior, when I 
connect the stick and open an application like Me-TV or VLC I get this 
message:
"Failed to get available frontend" or "There are no DVB devices available"
After running a w_scan it works, does someone know why?

Regards,
Gilles
